多项研究数据显示,我国居民无论是成年人、中老年人,还是学龄儿童普遍存在着锌摄入不足的‘潜在饥饿’问题,锌缺乏不仅会导致儿童偏食厌食、生长发育不良、矮小、瘦弱;而且也会使成年人免疫力降低,甚至导致男性不育或者女性妊娠受到影响等问题。如何从调整膳食结构入手,引导居民增加富含锌的食物的摄入,从而维持身体对锌的营养需求?我们采访了中国疾病预防控制中心营养与食品安全所微量元素营养室研究员杨丽琛。 A number of studies have shown that there is a universal problem of potential hunger for zinc deficiency in adults, middle-aged and elderly, or school-age children in our country. Zinc deficiency will not only lead to partial anorexia, poor growth and development, short stature and emaciation ; But also reduce the immunity of adults, and even lead to male infertility or women affected by pregnancy and other issues. How to start with the adjustment of dietary structure and guide residents to increase the intake of foods rich in zinc so as to maintain the nutritional needs of the body for zinc? We interviewed Yang Lichen, a researcher of the nutrition center of nutrition and food safety of China Center for Disease Control and Prevention.
